  • 자연어 처리 응용 분야에서 다양하게 이용할 수 있는 용어들을 자동적으로 획득하고, 나아가 이 과정을 점진적으로 반복하여 수행함으로써 획득할 수 있는 용어의 수를 증가 시키고 그 용어들 간의 의미적 관계도 얻을 수 있다. 점진적인 용어 획득을 위하여 용어의 형태에 변이 규칙을 적용하여 새로운 용어를 획득하는 과정을 반복한다. 우리는 변이의 종류를 단어간의 변이 뿐만 아니라 단어 내의 변이 그리고 이 둘을 결합한 복합 변이로까지 확장하여 새로운 용어 획득 과정을 더욱 다양화하는 기법을 제시한다. 실험은 확장된 변이 규칙으로부터 얻은 용어들 중에서 기존의 단어간의 변이로부터 획득한 용어들의 비율이 전체의 38.6%라는 사실로부터 변이의 종류 및 규칙의 확장이 획득할 수 있는 용어들의 수를 증가 시킬 수 있다는 것을 보여준다.

  • Fixed-point optimization utility software that can aid scaling and wordlength determination of digital signal processign algorithms written in C or C$\^$++/ language is developed. This utility consists of two programs: the range estimator and the fixed-point simulator. The former estimates the ranges of floating-point variables for automatic scaling purpose, and the latter translates floating-point programs into fixed-point equivalents for evaluating te fixed-point performance by simulation. By exploiting the operator overloading characteristics of C$\^$++/ language, the range estimation and the fixed-point simulation can be conducted just by modifying the variable declaration of the original program. This utility is easily applicable to nearly all types of digital signal processing programs including non-linear, time-varying, multi-rate, and multi-dimensional signal processing algorithms. In addition, this software can be used for comparing the fixed-point characteristics of different implementation architectures.

  • The purpose of this study was to evaluate the effects of multisensory(AVK: Auditory, Visual and Kinethetic) treatment on reading pronunciation with phonological prcessing - tensification, palatalization, and lateralization for the middle school students with delayed language development caused by mental retarded. Participants were three children with reading pronunciation difficulties in phonological processing. The following conclusions were arrived. First, three children are improved on tensifiication, palatalization, and lateralization by multisensory treatment program. Second, multisensory treatment was effective in facilitating generalization. Three children presented prominent generalization effcects in lateralization. Third, they were found to maintain partially their performance rates of the later phase of the reading with phonological processing intervention three weeks after the termination of the intervention.

  • 음성인식 결과는 다수의 후보를 생성할 수 있다. 해당 후보들은 각각 음향모델 값과 언어모델 값을 결합한 형태의 통합 정보를 갖고 있다. 여기서 언어모델 값을 다시 계산하여 성능을 향상하는 접근 방법이 일반적인 음성인식 성능개선 방법 중 하나이며 n-gram 기반 리스코링 접근 방법이 사용되어 왔다. 본 논문은 적절한 성능 개선을 위하여, 대용량 n-gram 모델의 활용 문제점을 고려한 문장 구성 어휘의 의존 관계 분석 접근 방법 및 일정 거리 어휘쌍들의 상호정보량 값을 이용한 접근 방법을 검토한다.

  • In order to considerably reduce the ambiguity rate, we propose in this article a disambiguation approach that is based on the selection of the right diacritics at different analysis levels. This hybrid approach combines a linguistic approach with a multi-criteria decision one and could be considered as an alternative choice to solve the morpho-lexical ambiguity problem regardless of the diacritics rate of the processed text. As to its evaluation, we tried the disambiguation on the online Alkhalil morphological analyzer (the proposed approach can be used on any morphological analyzer of the Arabic language) and obtained encouraging results with an F-measure of more than 80%.

  • Japanese does not exhibit deontic-epistemic polysemy which is recognized among typologically different languages. Hence, in Japanese linguistics, it has been debated which of the two types of modality is more prototypical. This study brings Chinese learner's acquisition data of Japanese modality to bear on the question of which of the two types of modality is more prototypical, using the Competition Model (Bates and MacWhinney 1981). The Competition Model notion of 'cues' as processing strategy adopted by learners reveals the continuity/discontinuity between these two modality domains.

  • Distributed object Computing, owing to the development of distributed computing, has improved the performance of distributed processing conducted between homogeneous and heterogeneous systems in network. However, it has failed to solve fundamental problems such as network overload and enormous requests demands by servers and clients. In this paper, we propose to design and implement an Object Migration system that uses the java language to tackle the mentioned problems. As the first step of the implementation of the system, we justify the characteristics of t도 mobile object model that keeps codes and states of an object. Implemented Object Migration System would accept objects being migrated to a specific node and support the virtual place in which objects could be executed automatically. Therefore, the Object Migration system we suggest could not only solve problems imposed to traditional distributed computing but also offer transparency of object migration between homogeneous and heterogeneous systems.

  • 최근 웹을 기반으로 한 계속적인 기술 발전에 따라 의사결정에 필요한 데이터의 요구는 점점 다양해지고 있으며 다양한 요구를 효과적으로 대응하기 위해 데이터 추출 방법에 대한 연구도 지속적으로 이루어지고 있다. 이에 본 논문에서는 자연어를 통해 사용자가 쉽게 원하는 자료를 추출 할 수 있는 방법론을 연구 하였다. 자연어 처리 기술에 대한 연구는 여러 방면에서 이루어지고 있는데 그 중에서도 본 논문에서는 기존의 자연어 처리 연구를 바탕으로 크게 3가지 형태로 연구 진행 하였다. 사용자가 입력한 정보를 바탕으로 유추하여 자연어를 처리하거나 이후 진행될 검색을 선 예측 하는 방법과 사용자 별로 검색되는 자연어를 통해 연관 관계를 설정하여 사용자에게 예측검색을 유도하는 방법 그리고 의사 결정을 위해 구축된 데이터베이스 스키마 정보를 이용하여 사용자가 쉽게 질의 문을 생성할 수 있도록 하는 방법론 연구이다. 본 논문을 통해 연구된 내용은 실제 구축하여 진행 하였고, 연구결과로 생성된 질의 문이 효과적으로 시스템에서 처리 되는 과정에 대한 연구도 함께 진행하고 검증하였다.

  • Ontology maintenance is a time consuming and costly process which requires special skill and knowledge. It requires joint effort of both ontology engineer and domain specialist to properly maintain ontology and update knowledge in it. This is specially true for medical domain which is highly specialized domain. This paper proposes a novel approach for maintenance and update of existing ontologies in a medical domain. The proposed approach is based on modified Ontology Maturing Process which was originally developed for web domain. The proposed approach provides way to populate medical ontology with new knowledge obtained from medical documents. This is achieved through use of natural language processing techniques and highly specialized medical knowledge bases such as Unified Medical Language System.
